List of Pokémon by gender ratio

Most Pokémon are either male or female. However, depending on the species, players are more likely to encounter a Pokémon of a specific gender than the other. Gender plays a vital role in breeding, as offspring inherit the species of the mother and compatible moves from the father. However, Pokémon of either gender can be used if the partner is a Ditto.

Unbreedable

1 ♀ : 7 ♂

These Pokémon normally appear as male, rarely female. This specific gender ratio is used to make it more difficult in breeding more of them since players usually get them as gifts or Fossils rather than catch them in the wild. All starter and Fossil Pokémon are in this group.
